Surrogate-Enhanced Fractional Programming for MIMO Device-to-Device Interference Networks
Zihan Jiao, Xinping Yi, Shi Jin +1
Interference management in multi-stream multi-input multi-output (MIMO) device-to-device (D2D) networks often leads to weighted sum-rate maximization with sum-log-determinant invol…
Rethinking Fractional Programming for Joint Uplink Scheduling and Power Control in Multicell Wireless Networks
Zihan Jiao, Xinping Yi, Shi Jin +1
This paper investigates the joint uplink scheduling and power control problem in a coordinated multicell wireless network, where at most one single-antenna user is allowed to acces…
Topology-Aware Coordination for Multi-Functional Low-Altitude Wireless Networks
Jiajun He, Han Yu, Yiran Guo +6
Low-altitude wireless networks (LAWNs) are expected to consist of multi-tier, heterogeneous terrestrial and non-terrestrial devices, where effective coordination is essential to fu…
Topology-Aware Integrated Communication, Sensing, and Power Transfer for Multi-User SAGIN
Han Yu, Jiajun He, Xinping Yi +3
In sixth-generation and beyond, space-air-ground integrated networks (SAGINs) extend network connectivity to space, thereby enabling broader service coverage. This paper proposes a…
Data-Driven Deep MIMO Detection:Network Architectures and Generalization Analysis
Yongwei Yi, Xinping Yi, Wenjin Wang +2
In practical Multiuser Multiple-Input Multiple-Output (MU-MIMO) systems, symbol detection remains challenging due to severe inter-user interference and sensitivity to Channel State…
A Low-Complexity Framework for Multi-access Coded Caching Systems with Arbitrary User-cache Access Topology
Ting Yang, Kai Wan, Minquan Cheng +3
This paper studies the multi-access coded caching (MACC) problem with arbitrary user-cache access topology, which extends existing MACC models that rely on highly structured and co…
